The NFFS Guide to Aluminum Casting Design: Sand and Permanent Mold is intended to provide those who specify and use aluminum castings with timely, accurate and relevant information regarding the properties, benefits, and advantages of sand and permanent mold cast aluminum. The Guide will serve as a ready reference for those involved in aluminum casting processes, aluminum casting design, aluminum alloys, heat treatment, and surface finishing of cast aluminum products. The Guide has been completely rewritten using both up-to-date and authoritative references, and expert input from a variety of sources. This reference manual is a join effort of the Non-Ferrous Founders' Society and the Center for Applied Research in Metal Casting in the Department of Industrial Technology at the University of Northern Iowa, Cedar Falls, Iowa.
